This paper describes the development of an innovative carbon nanotube-based non-woven composite sensor that can be tailored for strain sensing properties and potentially offers a reliable and cost-effective sensing option for structural health monitoring (SHM). This novel strain sensor is fabricated using a readily scalable process of coating Carbon nanotubes (CNT) onto a nonwoven carrier fabri...

Ultrasonic vibration was employed in blending the nanosilica into epoxy resin to manufacture hemp/kevlar/nanosilica-based composites, with an ultrasonic occurrence of 20 kHz and a 900 W capacity power. An probe utilized ensure consistent dispersion nanoparticles epoxy. The mechanical characteristics hemp/kevlar fiber reinforced epoxy/nanosilica mat form have been studied. Hand layup procedures ...

Epoxy-based nanocomposites were fabricated with different content of colloidal silica nanoparticles such as 10.0, 20.0 and 30.0 wt %, through solution casting. The covalent bonding interfaces, resulting from a ring-opening reaction between silica nanoparticles and epoxy matrix were confirmed by the Fourier transform (FT-IR) infrared spectroscopy. These nanocomposites were characterized for ...

Polymeric materials containing nanometer (nm) size particles are being introduced to provide compact shapes for low and medium voltage insulation equipment. The nanocomposites may provide superior electrical performance when compared with those available currently, such as lower dielectric losses and increased dielectric strength, tracking and erosion resistance, and surface hydrophobicity. All...

Composites with nanoparticles and polymers can improve the functionalities and existing formulations. In this work we synthesized Graphene Oxide and is incorporated into an epoxy based negative tone photoresist in different weight percentages. Thermal conductivity studies were carried out on those composites and it was found that 13 % by weight is the optimized loading to have an enhanced therm...

Polymer composites reinforced by carbon nanotubes have been extensively researched for their strength and stiffness properties. Unless the interface is carefully engineered, poor load transfer between nanotubes (in bundles) and between nanotubes and surrounding polymer chains may result in interfacial slippage and reduced performance. Interfacial shear, although detrimental to high stiffness an...

Fiber-reinforced polymer composites (FRCs) have shown great promise as high strength structural materials due to their high stiffness to weight ratio and their ease in processing. They have found extensive use in aerospace, automotive, construction, and recreational equipment material applications. Research in polymer-based nanocomposites (PNCs) has shown explosive growth in the past decade wit...
